Rotor dynamic balancing control method based on fuzzy auto-tuning single neuron PID

Abstract

In order to improve the control efficiency and balance accuracy of rotor automatic balance, a fuzzy self-tuning single neuron PID control method is proposed in this paper. Based on the single neuron PID control method, the fuzzy control theory is introduced to adjust the output gain K of single neuron PID control to realize single neuron PID control with variable step size. In order to verify the superiority of this method, the method we designed in this paper is compared with the traditional PID control method and the single neuron PID control method by the simulation and self-built experimental platform. Experiments and simulation results show that the fuzzy self-tuning single neuron PID control method has faster response time, less overshoot amount and fewer oscillation times than the traditional PID control method and the single neuron PID control method, and has strong robustness and good stability.

“…The new estimated values ofR k can be calculated according to Equation (22), and then the gain parameters can be calculated and renewed by replacing the parameter of R byR k in Equation (14).…”

“…If the system is stable at all discrete speeds, it can be assumed that the system is stable during the entire transmission period. When the speed is constant, Equation (10) is substituted to Equation (14) to obtain the following formula:…”

“…In 2017, based on the single neuron proportion integration differentiation (PID) control method, fuzzy control theory was introduced by J. Xu et al to adjust the output gain K of single neuron PID control to realize single neuron PID control with variable step size. Experiments and simulation results showed that the fuzzy self-tuning single neuron PID control method had the advantages of faster response time, less overshoot amount, fewer oscillation times, extreme robustness, and good stability [14]. Based on the dynamic model of a rotor system with time-delay, a strictly positive real system was built to satisfy the stability conditions of the adaptive control system.…”

“…The switching system is a concept in the field of control engineering. "Switching" as an idea was first introduced into 2 Complexity the control system from the switching servo system [10,[18][19][20][21]. It is determined by the switching rule to switch the subsystem, and only one subsystem can work at each moment [14][15][16][17][18][19][20].…”
